not like scores really matter past 760, and 720 at most banks, if a 760 bank doesn't give you the best rates just go to another one. Regardless what probably set your score down was AAOA for average age of accounts.

For instance if you had 3 cards and only 3 cards for 10 years your AAOA is 10 years. Add 2 new cards and then your AAOA dropped to 4 years. AAOA accounts for about 15% of your scores. this is the reason why most people have to be in their 40's for a close to perfect score (Fico CEO's words)

Regardless it's just a number, doesn't really matter. I don't even have a 2 year credit card history and I'm at AAOA of 9 months right now, and finished my 2nd successful churn and have over 100k in credit limits and multiple cards at the best rates possible. My Fico EQ was at 721, now it's down to 719 after 2 inquiries. To max out my cards but restrict my inquiries I app for banks that pull only certain credit bureaus. I did 2 on EQ EX and TU each for total of 6 apps, but only registers 2 inquiries to each bureau which is fine for me.

Remember bloggers aren't to blame because they post up their own experiences with credit score and drops in credit after app sprees. The damage for inquiries eventually maxes out. I went and applied for 20 things when I didn't know any better and got turned down for everything minus a Kays jeweler card. Once I removed EVERYTHING bad on my credit file by sending intention to sue letters to all my creditors which bad accounts, I applied for more cards was approved for everything with a 760 score and my credit score didn't budge at all. My credit scores are down a little now since I cashed out a lot of money from my credit card to buy a house. (cash only property) and my card company doesn't charge me cash advance fees which was ideal. Especially because I then transfered the balance to my parent's card, on their new card (i churn for them lol) then transferred it back 2 months later for a 0% transfer 0% for 12 month promotion.
